Fig. 6 1s a corresponding view, showing the writing as occurring at an intermediate position on the work-piece.

Fig. 7 is a corresponding. view, showing the pasteboard frame of the stencil supported over the line of writing, to receive impressions from type thereon.

The invention is herein illustrated as applied to an Underwood typewriting machine, although obviously it is applicable to other typewriting machines.

The drawings show a portion of the frame of a typewriting machinedesignated by the numeral 1; also the carriage 2, with platen frame 3 and platen '4 supported in said frame by its axle 5, which has the usual finger-piece'G and line-spacewheel 7, said linespace wheel being operated by pawl 8.

Fast upon the platen axle at opposite ends of the platen are gear wheels 9 with which are meshed racks 10 extending vertically at theforward side of said wheels, said racks being guided in their vertical movements'by retaining plates 11 pivoted uponthe platen axle and having forwardflanges 12 which hold the racks 10 to their gear wheels.

The racks 10 are united at their upper ends by a strip or bar 13 which extends said bar or strip carrying fingers 14, which depend therefrom, spaced apart, and lie against the front surface of the platen and about tangential thereto. Said fingers 14- ha ve inturned lower ends forming hooks or pockets 15, which are intended to receive the'lower edge of a workpiece. The bar 13 and fingers 14- form a work-holder arranged in upright position in' front of the platen. This work-holder is moved up and down in parallelism by the l cooperation of the rigidly connected gears 9 with the racks 10 (the latter rigidly united by cross bar 13), so that perfect line-feeding of the work-piece is insured, since the mere pressure of rolls to hold the card upon the platen and thereby linefeed the card, as heretofore, is no longer'depended upon, but in place thereof vissubstituted the positive mechanically effected line-feeding 'movement of the work-holder itself.

Said fingers 14-and racks-1O may for con- .ven-lence be curved toward their lower ends in a rearward direction, thereby allowing them to swing beneath the platenin descending, the swinging action thereof being ef fected by means of cam plates' 16 mounted ,upon the platen frame 3 at the opposite-ends the platen as by lugs17 and screws 18-, said plates having cam slots 19 to receive pins or projections 20, that extend from the ends of the bar. or strip 13. The pivotal re-' taining plates 11 for the raeks ,10:permit the 'curved portion of the cam against the platen.

and racks 10 in the first part of their travel,

move downwardly about in a. straight line, and when the pins 20 enter the forwardly slots, said fingers l4 and racks 10 are thenswung at their lower ends rearwardly, causing said fingers 14 and racks 10 to avoid striking portions of the machine frame which would be in their path ifthey continued to descend in a vertical direction, and said cam slots, being curved in a slightly rearward direction toward their lower ends, serve to guide the fingers 14, so that they may properly exercise their function of presenting the workpiece to the platen surface. I

Taking the bar 13 with the racks 10 and fingers 14 as a unit, it will be noted that the flanges 12 of the pivotal retaining plates 11, by holding the racks in mesh with the gear wheels throughout their reciprocating movement, serve to maintain the relation of the fingers 14 with respect to the platen surface to. hold the work-piece carried by said fingers lifn operative position before said platen surace.

At Fig. 5 a work-piece, as 22, is shown inserted within the "pockets or hooks 15 of the fingers 14, which hold the middle portion of the work-piece closely to the platen surface at the printing line; and spring fingers or extensions 23 (from said fingers 14), are

"bent over and downwardly behind the bar upper portion in position to receive writing at about the first line thereon, and the spring fingers have begreater tension 1 which is held firmlycome contracted, and exercise upon the work-piece,

When desirable to write upon the upper frame portion or margin of the workiece, as for making notes, etc., that upper ine upon the platen, as shown in Fig. 7. In this-instance, the spring fingers 23, which at their ends stillbear against the upper 'edge of the workpiece, frame of margin,

rame ortion .is retracted to be over the printing Fig. 6, the workhave become fully contracted, to exercise their maximum force;

Tholimiting slots 19 in the plates 16-restrict the backward oscillation of the-plate ,plaitenl musing a bar 1. that the work-piece,

m pth, may, after insertion in'the holder, be :moved down to position forwriting the first reon, lor ior writing uponthe top and lso-limit the advance of V the S n s ya ripheriesnpon the gear wheels comes into actual" service in the operation aforesaid, obviously segments including a "suliicient num ber oi teeth might be employed in place of the gearwheels.

Variations may: be resortedto within the scope ofthe'invention, and portions of the improvements may be used Without others. Iaving thus described my invention, I
